B2409S-1WR3 产品概述
B2409S-1WR3 是 YLPTEC（易川）推出的一款微小体积、隔离型非稳压单路 DC/DC 模块，额定输出功率 1W，专为板上需要产生与输入电源隔离电压的场合设计。模块采用 DIP 封装，体积小巧（11.6 × 6 × 10.16 mm），便于通过孔插件或空间受限的 PCB 布局使用。
一、主要电气特性
- 输入电压：21.6V ~ 26.4V（定电压输入，建议输入电压变化在 ±10% 范围内）
- 输出电压/电流：9V / 最大 111mA（单路输出）
- 输出功率：1W，转换效率典型值 89%
- 隔离强度：1.5 kV (Vrms)，满足常见的 1500V 级别隔离要求
- 开关频率：260 kHz；静态电流：8 mA；输出纹波噪声：30 mVp-p
- 最大容性负载：1000 μF
二、保护与可靠性
模块内置短路保护、自动故障恢复和过热保护功能，能在异常工况下自动限制或恢复输出，提升系统可靠性。工作温度范围宽，-40 ℃ 到 +105 ℃，适合工业级环境下长期使用。
三、典型应用场景
B2409S-1WR3 适用于输入电压较稳定、需要电气隔离但对输出稳压精度要求不高的场合，例如：
- 纯数字电路与逻辑隔离电源
- 继电器驱动与接口电源
- 数据交换、电平移位和抗干扰隔离
- 一般低频模拟电路（需注意输出纹波要求）
四、设计与布局建议
- 输入侧建议加入旁路电容以抑制输入纹波，输出侧根据负载和纹波指标配置低 ESR 电容；注意单元最大容性负载为 1000 μF，不宜超限。
- 模块为小功率器件，布板时保持良好散热路径及周边通风，必要时进行温升评估并在高温环境下进行功率降额。
- 对于需要满足更高安全标准的应用，留意爬电距离与安装间隙，按照系统绝缘要求布置接地与隔离区。
- DIP 封装利于手工插装与测试，但在高振动场合需采取可靠固定措施以防焊接或插拔松动。
五、选型要点与注意事项
- 若系统输入电压波动超过 ±10%，或需精密稳压输出，应选用带调节或更高功率的模块。
- 对输出噪声敏感的模拟前端，应在模块输出做额外滤波或选择低噪型电源方案。
- 模块适合用于对隔离等级有中等要求的工业与通信设备，若需更高隔离等级或更大功率，请咨询厂家系列产品。
总结：B2409S-1WR3 以其小体积、高效率与基本保护功能，适合在板级电源设计中作为隔离电源源头使用，尤其适合数字隔离、电平转换及继电器/接口驱动等场合。在使用时注意输入稳定性、输出容性负载限制与良好散热设计，可获得可靠的长期运行表现。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Sourcing availability signal
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
Examples of how common component sourcing requests are organized.
Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.
The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
